The cost varies, depending upon the centre where you study. I've just completed CCNA and got the exam. The centre where I've been studying charges 400GBP per semester (2 semesters per year) but I know of one that charges only 100GBP per semester. I have no idea why there's such a difference but, If I'd known about the second one earlier, I would have transferred!

Thanks for the info! I get to do my CCNA for free as its funded by my university, well... I suppose Ive paid in a roundabout way...

I seem to be really struggleing with subnetting, I can just about do it with pen and paper however im sure my lecturer said we wernt alloud any during the exam and had to do it off the top of our heads. Im going to take them anyway just in case.

I passed my CCNA some years ago with flying colors. I would have suggested that you learn subnetting inside and out. Its not just about knowing it, its about being able to do it quickly. Too many exam questions indirectly rely on you being able to do it. I've been doing it for years, but even still I was worried I choke under pressure.

When you get to the exam, before the time starts, I wrote down my subnetting charts on the scratch paper they provide. It took less than five minutes and when I was done I started the exam for time. I constantly referred back to the chart and knew that those figures were correct. It was one less thing that I had to think about.

The costs vary very much from what I know, depending where you take it. If you are still at school or university you may ask one of the uppers if you can make it through your school (you can also ask your company, often they are glad to see that their employes want to improve theirselfs and pay you for it).

There is an extremely good site for learning anything to do with the CCNA exam requirements. It is:http://www.howtonetwork.net.&nbsp; It is a commercial site costing around US$9 a month which is very small for the level of information presented.It provides a system that allows "in the head" subnet calculation that is both quick and accurate.I am still a subscriber even though I am studying the CCNP.I can not stress how useful I have found the site. And NO I am not affiliated with it in any way.
